I'd like to change the type of a struct rlimit's fields from quad_t to
a new type rlim_t, which will be defined in <sys/types.h>.
Most programs from the Net still use "long", which doesn't work very
well with our 64bit rlimit fields. If we use rlim_t, the maintainers
can use that type in their programs, and provide their own definition
of the traditional "long" on systems that don't provide it.
This is like OSF/1.
